build: fix building on apple silicon

[radkomih]

Hi, while I was exploring the FuzzyVM I've encountered this error:

./FuzzyVM build

/Users/USER/go/pkg/mod/github.com/ethereum/go-ethereum@v1.11.5/crypto/blake2b/blake2b_f_fuzz.go:43:2: undefined: fSSE4

typechecking of . failed

I am on Apple Silicon, which is causing the issue so I've included a fix.

Hmm this hardcodes the architecture to arm64, thats not something that we should do

Yeah, it's ugly, but it was more to illustrate the problem. if you want, I can open an issue?
aslo close this one.

Hmm does compiling FuzzyVM itself work for you? I'm in the process of removing go-fuzz from the codebase in favor of the builtin fuzzer. I also recently updated all dependencies. Could you try to do a go build and report back if that works? If so it will work on m1 once I switched to the builtin fuzzer

Compiling the old version of FuzzyVM (with go-fuzz) works by providing the GOARCH=amd64 when running ./FuzzyVM build.

Now I've tried to use the most recent changes (without go-fuzz)

go build

it works fine, but I still need to change the GOARCH

GOARCH=amd64 ./FuzzyVM run

otherwise it fails
